To Infinity and Beyond, a Journey in Scaling

Since the beginning of 2020, the ThousandEyes (Cisco) Endpoint product has grown by a factor of 25! Scaling systems to support a high number of users while maintaining the same level of performance is a challenge that all high growth products will face.

In this session, we will present the lessons we have learned in our scaling journey so far, some of which were painful, all of which were enlightening. Along the way, we will deep dive on some of the architecture decisions that were made, and talk about the tricky art of uncovering scaling and performance bottlenecks.
